NSW 2500 Census 2021 + Live DA Data

Wollongong

Apartment living shapes Wollongong more than detached housing: 77.6% of homes are apartments, while the 12.2% vacancy rate is high for a renter-majority suburb. Its 20,446 residents live across just 5.76 square kilometres at a density of 3,546.9 people per square kilometre. The population is relatively young, with a median age of 35, and 33.7% were born overseas, 12.1 percentage points above the national average. That international and professional profile is supported by 48.0% university participation, 17.9 points above the national figure. The dense, apartment-led form gives Wollongong a different feel from nearby Mount St Thomas, where detached housing is more typical, because smaller households and central services support compact living.

Buyers should price Wollongong by dwelling type rather than relying on a suburb-wide house impression. Apartments account for 77.6% of homes, compared with 13.9% separate houses, while 52.7% have 2 bedrooms and 11.9% have 0 or 1 bedroom. That mix suits singles, couples and downsizers because the average household size is 2.0. The monthly mortgage figure is $1,950 and mortgage payments equal 29.1% of household income, so borrowing capacity still needs stress testing. Household income sits at the 49.2 percentile, giving a middle-of-distribution affordability context rather than a premium-income buffer. Buyers should compare strata costs, parking and outlook carefully, particularly against nearby Mount St Thomas where detached housing is more typical.

For Investors

Wollongong has a substantial rental market, with 55.2% of households renting, higher than the 17.9% share paying a mortgage. Weekly rent is $410, but the 12.2% vacancy rate signals that tenant demand may be less predictable than in a tightly supplied market. This matters because apartment investors need to allow for leasing periods, building competition and strata expenses rather than assuming strong occupancy. Development activity is also material, with 180 applications recorded over 12 months, while forecast rent growth is 41.4%. Overseas migration is the primary growth driver and may support tenant demand, but the apartment-heavy supply pipeline means location, building quality and transport access are important to returns.

Compared with nearby Mount St Thomas, Wollongong has a markedly more apartment-led housing market, with apartments representing 77.6% of homes versus 13.9% separate houses. Renting is the dominant tenure at 55.2%, while 24.4% of homes are owned outright and 17.9% are mortgaged. The bedroom profile is compact: 52.7% of dwellings have 2 bedrooms, 29.0% have 3, and only 6.4% have 4 or more. A 12.2% vacancy rate gives renters more choice but also indicates substantial available supply. This structure reflects high density, an average household size of 2.0 and a central employment base, making apartment condition, storage, parking and body corporate costs more important than land size alone.

Transport to Work

Wollongong provides dense, service-rich living, with 20,446 residents across 5.76 square kilometres and a density of 3,546.9 people per square kilometre. Compared with public transport use at 3.6%, car driving is much higher at 47.3%, although 10.9% walk or cycle and 35.0% work from home. Six government schools provide local coverage: 4 primary schools, 1 secondary school and 1 school for specific purposes. Families should check enrolment zones against the exact address because boundaries can cross nearby suburbs. IRSAD is in decile 6 compared with IRSD decile 5, indicating a mixed socioeconomic setting. A street-level safety check remains sensible, including current police information, lighting, building access and the feel of the commute at different times.

Established

Wollongong's growth outlook is active rather than static. The forecast annual trend is 1.99%, with overseas migration identified as the primary driver. Population change across the wider area is 27.9% over 10 years, higher than a flat trajectory, while the gentrification forecast has a score of 50 and an Active stage. The shift assessment also records an Active gentrification stage with a score of 45. The trajectory is Aging, with the senior share up 3.9 percentage points and the young share down 0.5 points. Rent growth of 41.4% adds pressure to housing costs, but the combination of migration and central employment should keep demand supported because healthcare, education and professional services provide recurring local jobs.

How to read these comparisons

Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.

Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.

Data sources: ABS 2021 Census (demographics, income, tenure), state education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
